CVE-2015-0261 Red Hat Update for tcpdump (RHSA-2017:1871)

The tcpdump packages contain the tcpdump utility for monitoring network traffic.

Multiple out of bounds read and integer overflow vulnerabilities were found in tcpdump affecting the decoding of various protocols. An attacker could create a crafted pcap file or send specially crafted packets to the network segment where tcpdump is running in live capture mode (without -w) which could cause it to display incorrect data, crash or enter an infinite loop.
